=======================  First Aid Measures  =======================

First Aid:INHALATION: IMMEDIATELY REMOVE VICTIM TO FRESH AIR. IF
    BREATHING HAS STOPPED, GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS

    CYLINDERS COOL.
Unusual Fire/Explosion Hazard:CYLINDER EXPLOSION MAY OCCUR UNDER FIRE
    CONDITIONS.

==================  Accidental Release Measures  ==================

Spill Release Procedures:EVACUATE AND VENTILATE AREA. PREVENT ESCAPE OF
    GAS AND REMOVE SOURCES OF IGNITION IF POSSIBLE. REMOVE LEAKING
    CYLINDER TO EXHAUST HOOD OR SAFE OUTDOORS AREA.

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE IN A  WELL VENTILATED AREAS
    ONLY. KEEP VALVE PROTECTION CAP ON CYLINDERS WHEN NOT IN USE AND
